Just thought I'd report any little hitches I find which might not be known about, will keep updating as I find them, after my first playthrough everything went absolutely fine, loaded up fine, played without any hiccups etc. Things i noticed were...
1. The icon for "not one step back" turns into the Wehr forced retreat symbol in the area where you select it, rather than the mother russia one on the command tree.
2.ZIS AT gun uses the american 57mm icon
3.Once you've won a game the "Victory" box that appears is the one used for Wehr.
Nothing major at all really, just small aesthetic things, you might know about them already and if so apologies
Cheers
